Total synthesis of callystatin A, a potent cytotoxic polyketide from the marine sponge, Callyspongia truncata
摘要:
A first total synthesis of callystatin A (1), a potent cytotoxic polyketide from the marine sponge Callyspongia truncata, has been achieved by use of an E-selective Wittig olefination and asymmetric Evans aldol condensation as the key reactions. Thus, the absolute stereostructure of 1 previously established by us was confirmed. (C) 1998 Elsevier Science Ltd. All rights reserved.

We wish to report here our initial efforts towards the total synthesis of callystatin A, describing the synthesis of the C13-C22 fragment. This asymmetric approach uses an efficient syn-aldol reaction, and a diastereoselective epoxidation of an allylic alcohol with m-CPBA followed by epoxide opening with Me2CuLi.

A highly convergent and efficient totalsynthesis of the potentantitumor polyketide (−)-callystatin A is described. The synthesis required 19 steps from N-propionyl oxazolidinone 23 and produced the desired product in 3.5% overall yield.
